Digital technology is gradually expanding its field and has a great influence on various fields of dentistry. Recently in digital dentistry, the importance of superimposing various 3-dimensional (3D) image data is emerging, in order to utilize gathered data effectively for diagnosis and prosthesis fabrication. Integrating data from facial scans, intraoral scans, and mandibular movement recordings can create a virtual patient. A virtual patient is formed by integrating digital 3D diagnostic data such as intraoral and extraoral soft tissues, residual dentition, and dynamic occlusion, and the results of prosthetic treatment can be evaluated virtually. The patients in this case report were a 37-year-old female whose chief complaint is that the appearance of the existing prosthesis was distorted and a 55-year-old female patient whose anterior prosthesis needed to be refabricated after the endodontic treatment. 3D facial scans were obtained from each patient, and the patient's mandibular movements were recorded using ARCUS Digma 2 (KaVo Dental GmbH, Biberach an der Riss, Germany). The collected data were integrated on computer-aided design (CAD) software (Exocad dental CAD; exocad GmbH, Darmstadt, Germany) and transferred to a virtual articulator to create a digital virtual patient. The temporary fixed prostheses were designed, restored, and evaluated, and it was reflected into the final restorations. With the aid of the virtual dental patient, accuracy and predictability could be increased throughout treatment, simplifying the occlusal adjustment and clinical evaluation with improved esthetic outcomes.

In order to develop a bodice prototype suitable for obese women in their 20s, this study compared and analyzed a total of five pattern system methods, including prototype of France and Japan, one prototype for education in Korea and two prototype for industries in Korea. Through this, this study attempted to investigate the bodice pattern system suitable for the development of plus-size women's clothing. For the pattern drafting, pattern 1 was applied with the most body dimensions such as interscye fold front, interscye fold back, bust circumference, neck circumference, and waist back length, and pattern 2, pattern 4, and pattern 5 were made based on bust circumference and waist back length. As a result of the appearance evaluation, Pattern 3 was evaluated as the best pattern in all items except for the suitability of the center front length and the suitability of the side waist circumference position. However, it was evaluated as inappropriate in items such as the vertical side line, the suitability of the side waist circumference line position, the suitability of interscye fold back position and shape, and the suitability of the back shoulder dart position. Most of the pattern drafting methods are based on the size of the bust circumference, but other institutional methods are considered necessary when setting the neck circumference and shoulder length for 20s obesity women. In addition, it is also required to develop a method for setting the front center length due to abdominal protrusion.

On the moon as well as the earth, one of the easiest ways to understand geological formation history of any region is to observe the stratigraphy if it is available, the order in which the strata build up. By analyzing stratigraphy, it is possible to infer what geological events have occurred in the past. Mare Nubium also has an unique normal fault called Rupes Recta that shows stratigraphy. However, a rover moving with wheels is incompetent to explore the cliff since the Rupes Recta has an inclination of 10° - 30°. Therefore, a quadruped walking robot must be employed for stable expedition. To exploration a fault with a four-legged walking robot, it is necessary to design an expedition route by taking account of whether the stratigraphy is well displayed, whether the slope of the terrain is moderate, and whether there are obstacles and rough texture in the terrain based on the remote sensing data from the previous lunar missions. For the payloads required for fault surface exploration we propose an optical camera to grasp the actual appearance, a spectrometer to analyze the composition, and a drill to obtain samples that are not exposed outward.

Makeup is the most common way to improve a person's appearance. However, since makeup styles are very diverse, there are many time and cost problems for an individual to apply makeup directly to himself/herself.. Accordingly, the need for makeup automation is increasing. Makeup transfer is being studied for makeup automation. Makeup transfer is a field of applying makeup style to a face image without makeup. Makeup transfer can be divided into a traditional image processing-based method and a deep learning-based method. In particular, in deep learning-based methods, many studies based on Generative Adversarial Networks have been performed. However, both methods have disadvantages in that the resulting image is unnatural, the result of makeup conversion is not clear, and it is smeared or heavily influenced by the makeup style face image. In order to express the clear boundary of makeup and to alleviate the influence of makeup style facial images, this study divides the makeup area and calculates the loss function using HoG (Histogram of Gradient). HoG is a method of extracting image features through the size and directionality of edges present in the image. Through this, we propose a makeup transfer network that performs robust learning on edges.By comparing the image generated through the proposed model with the image generated through BeautyGAN used as the base model, it was confirmed that the performance of the model proposed in this study was superior, and the method of using facial information that can be additionally presented as a future study.

Forensic entomology is a study that purposes at field reconstruction through insects attracted to carcasses, and has been mainly studied using carcasses such as a pig and chicken. Therefore, this study was conducted to find out if there is a singularity by using the carcass of water deer with different conditions and shapes of the hair quality and to find out the appearance of a necrophagous insect. The water deer carcass was received from the Jeollanam-do Wildlife Rescue Management Center and research was conducted. From May 19 2021 to July 2 2021, the decay progress of the carcass was observed for about 6 weeks. A total of 51 species of 21 families in 4 orders of insects were collected. Even after the carcass completely decays, even at the stage where the activity of other insects is not observed, insects such as Dermestidae and Tenebrionidae are collected from the hairs and leather of water deer carcass until the last. It was confirmed that insects of the order Coleoptera other than Diptera can be used as forensic entomological data related to the decay of carcasses with fur.

Reproductive disorders in cows cause economic loss in livestock farms. This study was carried out to investigate the incidence of endometriosis in the uterine of Korean indigenous cow (Hanwoo). In the present study, the uterine of 25 cows was provided by the slaughterhouse. As a result on a visual examination of the uterus, 18 out of 25 were visually normal, and 7 uteruses (28%) appeared rather pale and showed purulent or mucosal symptoms in Uterine horn. However, the results of hematological analysis showed that both RBC and WBC were normal and showed no signs of systemic inflammation, indicating 7 cows showed asymptomatic endometriosis. The inflammatory uterus (28%) showed a wide range of pathological conditions that elicit an inflammatory response, such as serous exudate and bleeding. Histological and microscopic analysis in the inflammatory group demonstrated that there was swelling of the uterine glands, and neutrophil, basophil, and lymphocyte appeared in the uterine gland. Moreover, plasma cells and hemosiderin-laden macrophages were increased in the endometrial stroma, which lead to inhibit pregnancy by suppression of the synthesis of pregnancy hormones, and the appearance of hemosiderin-laden macrophages is an indicator of intracellular bleeding. In summary, hematologically, it is a normal diagnosis in Korean indigenous cows, however, when the uterus was extracted and investigated microscopically, the asymptomatic endometriosis were evident. In order to achieve the goal of healthy cow management and breeding within 2 weeks after birth, cows' uterus should be washed, disinfected, and through thorough the hygiene management, it aims to prevent asymptomatic endometriosis to produce healthy offspring and reduce the breeding interval.

The Multi-Object Goal Visual Navigation(MultiOn) is a visual navigation task in which an agent must visit to multiple object goals in an unknown indoor environment in a given order. Existing models for the MultiOn task suffer from the limitation that they cannot utilize an integrated view of multimodal context because use only a unimodal context map. To overcome this limitation, in this paper, we propose a novel deep neural network-based agent model for MultiOn task. The proposed model, MCFMO, uses a multimodal context map, containing visual appearance features, semantic features of environmental objects, and goal object features. Moreover, the proposed model effectively fuses these three heterogeneous features into a global multimodal context map by using a point-wise convolutional neural network module. Lastly, the proposed model adopts an auxiliary task learning module to predict the observation status, goal direction and the goal distance, which can guide to learn the navigational policy efficiently. Conducting various quantitative and qualitative experiments using the Habitat-Matterport3D simulation environment and scene dataset, we demonstrate the superiority of the proposed model.

The film enters the color film from black and white, and the screen image changes qualitatively. The color in the film not only has the reproduction function of the restoration object like the objective appearance, but also has the function of conveying different subjective emotions. It can express the color and can't express it. The artistic effect conveys the information content that the story itself can't convey, so the color of the film becomes an important part of the film language. The color in the film is presented on the screen in the form of single-screen color, scene color, full-color color tone, and various color chains designed according to different contradictions and conflicts. Because the film art and art means are assembled by montage, he colors in the picture also form a montage form. People call it "color montage". People's subjective nature of color criticism and acceptance of color language also depend on various local tones. The accurate expression of the relationship, the unique attribute of color determines that the color must enter the structural state in order to express its unique charm. The color of the film only has the real aesthetic value when it enters the level of "color structure". This paper studies the color of Chinese and Western films from the differences between the color thinking of Chinese and Western film directors and the cultural implication of Chinese and Western film colors. The western film director emphasizes the structure of color and pays attention to the use of tonal montage to convey the characters. Emotions reflect the characteristics of a subjective color. Beginning with the "fifth-generation" director of Chinese film, the new journey of film color language has been opened. In the process of blending love and scenery, the film style of "image-in-one" has been achieved.
